Description The double-sheet monitoring systems from Leuze electronic reliably prevent the infeed of multiple-ply sheets. This helps reliably prevent damage and the creation of scrap in paper and cardboard pile processing machines. The systems operate on the basis of different physical principles and cover practically the entire range of applications. The systems for splice inspection and for multi-lane label inspection primarily detect splices or labels which are processed on roll machines. A maximum of 10 lanes can be detected by one system.
Typical applications
  • Double sheet detection of
    • Paper sheets
    • Cardboard sheets
    • Films
  • Splice inspection (VSU 12)
  • Multi-lane label inspection  (VSU 15)
